Last season my riding mower, which is a Craftsman YT3000 with a 21 HP Briggs & Stratton, began taking two or three cranks to spark and start up.
We have had a warm winter, and it began refusing to start when the temperature is below freezing. The mower is about three/four years old so I assumed the battery. The battery tester showed the battery to be fine, but I replaced it with a known good battery, though the problem with starting up has continued. On warm (above freezing temperature) days it starts up.
One morning it was 40 degree (F) out, and foggy. It would not start. Tried a couple times, then waited until about 1/2 hour after the fog cleared and it started up. This reminded me of a recent day, it had finished raining and I don't do anything in the yard after a rain but I did want to drive the mower into the garage to work on it, and it would not start.
What could prevent the mower's engine from starting when temperature is below freezing or above freezing temperature and there is high humidity?
